SUMMARY OF WORKS AND SERVICES UNDERTAKEN
- Above ground foundation (pile cap) founded on pre-cast concrete driven piles
- Poor ground conditions including contaminated Subsoil
- Extensive works to locate and identify existing services
- Cabling to new substation kiosks
- Working within a live wine distribution center
The project comprised construction of a reinforced concrete foundation supported on driven pre-cast concrete piles. It took place within a wine distribution centre which required regular interface with the customer to ensure there was no disruption to the distribution operations. Throughout the project we had to adhere to the strict security measures on site and incorporate those into our own site management procedures.
This project was unusual as the foundation was designed to be entirely above ground in order to minimise working in the extremely poor and heavily contaminated ground. The foundation required approximately 600m3 of concrete which was poured in one day with no disruption to the distribution centre’s operations.
As the foundation was heavily reinforced we recognised that placing the concrete and achieving adequate compaction would be difficult. We therefore worked with our concrete supplier and the foundation designer to develop a flowable self-compacting concrete incorporating synthetic fibres to meet the required design strength and durability.
The initial site works involved cutting and breaking out an existing concrete slab within the wine distribution centre. Our investigation works identified uncharted live water and gas mains within the foundation footprint. This required the foundation to be relocated to avoid any services clash. We undertook further investigation works to ensure there were no services in the new location.
These additional works inevitably carried a risk to the programme. To mitigate this risk, we accelerated our programme, by employing additional resource and working weekends. In addition, we revisited the concrete specification to utilise a mix which would achieve the necessary design strength in a shorter period. As a result, there was no delay to the delivery and installation of the turbine.
A successful project with a new client that was delivered on time.
